Existing literature highlights significant income loss due to Post-Harvest Loss (PHL) across the fisheries value chain in developing countries like Bangladesh. This is attributed to inappropriate fishing tools, poor infrastructure, inadequate storage facilities, and inefficient transportation. This study estimated PHL and its determinants in Bangladesh's marine fisheries using the Questionnaire Loss Assessment Method (QLAM) based on data collected from 1132 respondents, including fishermen and traders, from October 2019 to March 2021. The results reveal that physical, market, and monetary PHL in marine fisheries are 0.82 %, 6.41 %, and $228.52 per ton, respectively. Annually, the country loses approximately $151 million due to PHL in marine fisheries, with the highest market losses in Snapper, Pomfret, and Hilsa fish. The main reasons for PHL include the duration of fish remain in the net after being caught, insufficient ice, lack of insulated containers and storage facilities, delayed marketing, and oversupply. The study suggests adopting modern harvesting technology, enforcing regulations for scientific gear, and increasing storage capacity at landing and selling points to reduce PHL in marine fisheries.
现有文献强调,在孟加拉国等发展中国家,渔业价值链中的产后损失(PHL)导致了巨大的收入损失。这归因于捕鱼工具不当、基础设施差、储存设施不足以及运输效率低下。本研究基于2019年10月至2021年3月从包括渔民和贸易商在内的1132名受访者收集的数据,使用问卷损失评估法(QLAM)估算了孟加拉国海洋渔业的产后损失及其决定因素。结果显示,海洋渔业中的实物产后损失、市场产后损失和货币产后损失分别为0.82%、6.41%和每吨228.52美元。该国每年因海洋渔业的产后损失约为1.51亿美元,其中笛鲷、鲳鱼和孟加拉鲥鱼的市场损失最高。产后损失的主要原因包括鱼被捕后留在网中的时间、冰量不足、缺乏隔热容器和储存设施、销售延迟以及供应过剩。该研究建议采用现代捕捞技术、执行科学渔具法规,并增加上岸点和销售点的储存能力,以减少海洋渔业的产后损失。
